I'm really new to this, if fact just started 4 weeks ago. I'm trying to calculate the difference between to time.
I know where i'm going wrong just don't know how to rectify it.
Got time in and got time out, but time is in 60 minutes and not 100.
Please help.

int convert(char time[5])

{
int time_mins;
int int_time[4];

int_time[0]=time[0]-'0';
int_time[1]=time[1]-'0';
int_time[2]=time[2]-'0';
int_time[3]=time[3]-'0';

time_mins = int_time[0]* 1000 + int_time[1] * 100 + int_time[2] * 10 + int_time[3];
return time_mins;



}

void calctime ()
{
cout<<""<<endl;
cout<<" Please enter the start time of your call"<<endl;
cout<<""<<endl;
cin>> chstart;
cout<<""<<endl;

starttime = convert(chstart);
cout<<""<<endl;
cout<< starttime;
cout<<""<<endl;

cout<<""<<endl;
cout<<" Please enter the time your call ended"<<endl;
cout<<""<<endl;
cin>> chend;
cout<<""<<endl;

Endtime = convert(chend);
cout<<""<<endl;
cout<< Endtime;




totmins = (Endtime - starttime);

cout<<""<<endl;
cout<<" Your total minutes are: "; cout <<totmins;
cout<<""<<endl;


tothrs =(totmins / 60);

cout<<""<<endl;
cout<<" Your total hours are: "; cout <<tothrs;

cout<<""<<endl;
}

So, what's stopping you from changing the 100 into a 60? And thus, the 1000 into 600?

The way I see it... Well, it's all pretty blurry

I know that sounds like it should work but it doesn't. But thanks anyway

Changing it to 60, respectively 600 will make that part of the code work (for if the characters entered are in the format: "1230" for "12:30").

What's not working must be somewhere else. One thing I noticed is that your variables starttime and Endtime are not declared anywhere, and that the sub that is supposed to read the time is never called. I guess you didn't post the full code. Please do and we can find where the problem lies. Also, it helps if you tell what input you used and what output you got (and how that's wrong).

Look for the comments (//) I added. The code worked for me.
